Definitions
- the present invention relates to pharmaceutical and cosmetic compositions based on benzoyl peroxide and quaternary ammonium salts and their use, especially for the treatment of acne.
- the etiopathology of acne although poorly defined, originates in the formation of a characteristic lesion: the comedo. This results from obstruction of the pilosebaceous canal as a result of dyskeratinization of the infundibulum zone of the canal. The main effect of the obstruction is hyperproliferation of the resident skin strains, which then triggers an inflammatory reaction of the body.
- benzoyl peroxide has proved for many years to be a particularly interesting keratolytic agent, further having good bacteriostatic properties.
- benzoyl peroxide was then combined with the antibiotics.
- the latter has, in particular, been associated with erythromycin (FR-A-2378523).
- antibiotics associated or not with benzoyl peroxide have the major disadvantage during prolonged use, to make the bacterial flora resistant. They become less active during subsequent treatments. (LEYDEN JJ, J. Am Acad Dermatol 8 (1) 41-45 (1983)).
- Stable detergent compositions possibly used for the cleaning of the bit, which can contain simultaneously a quaternary ammonium surfactant such as benzalkonium chloride, cetalkonium chloride, cetylpyridinium chloride, benzethonium chloride or cethexonium bromide and benzoyl peroxide (FR-A-2328039).
- a quaternary ammonium surfactant such as benzalkonium chloride, cetalkonium chloride, cetylpyridinium chloride, benzethonium chloride or cethexonium bromide and benzoyl peroxide (FR-A-2328039).
- the Applicant has just discovered, quite surprisingly, that it is possible to obtain stable compositions in the treatment of acne, cutaneous ulcer, and generally in the treatment of dermatoses and skin disorders. , by associating benzoyl peroxide with certain quaternary ammonium derivatives.
- benzoyl peroxide can be used at low doses, with the advantage of improving skin tolerance.
- compositions according to the invention are well tolerated by the body. They have very good antibacterial properties, without inducing resistance of strains, they are keratolytic, bacteriostatic, especially vis-à-vis Propionibacterium Acnes which is one of the main germs responsible for acne and are active in treatment and reduction of the number of comedones.
- compositions according to the invention are suitable for the treatment of cutaneous disorders and dermatoses, such as, in particular, acne and cutaneous ulcer.
- the present invention therefore relates to a topical pharmaceutical and / or cosmetic composition containing benzoyl peroxide and at least one quaternary ammonium salt such as those described below.
- the invention also relates to a cosmetic treatment method implementing such an association.
- composition intended for a topical application in accordance with the invention is essentially characterized in that it contains, in a physiologically acceptable medium, benzoyl peroxide and a quaternary ammonium salt chosen from alkyl sulphates or sulphonates, aryl sulphonates and quaternary ammonium alkyl aryl sulfonates.
- X ⁇ denotes an alkyl sulphate or sulphonate anion, aryl sulphonate or alkyl aryl sulphonate.
- Particularly preferred anions are chosen from the anions of the following formulas:
- compositions may be in the form of solutions, emulsions, suspensions, gels or dispersions, containing at least one compound corresponding to formula (I) in concentrations of between 0.01 and 25% by weight, relative to the total weight of the composition and preferably between 0.1 and 5% by weight and benzoyl peroxide in concentrations of between 0.1 and 20% by weight relative to the total weight of the composition and preferably included between 0.5 and 10% by weight.
- compositions in accordance with the invention may also contain foaming or emulsifying surfactants, polymers such as cellulose and its derivatives, guar gum, heterobiopolysaccharides, polyacrylic acids and their derivatives, poly- ⁇ -alanine, ethers or esters of polyethylene glycols, colloidal silica, superfatting agents, emollients, wetting agents, pH regulators, penetration agents, preservatives, sunscreens, perfumes, dyes and / or pigments having as their function of coloring the skin or the composition itself and any other ingredient usually used in compositions intended for topical application.
- foaming or emulsifying surfactants polymers such as cellulose and its derivatives, guar gum, heterobiopolysaccharides, polyacrylic acids and their derivatives, poly- ⁇ -alanine, ethers or esters of polyethylene glycols, colloidal silica, superfatting agents, emollients, wetting agents, pH regulators, penetration agents, preservatives
- the galenic forms mainly conditioned for the topical route are especially in the form of solutions, creams, milks, gels, dispersions or microemulsions more or less thickened, soaked swabs, ointments, sticks or in the form of soap bars.
- Another subject of the invention is therefore also constituted by the use of pharmaceutical compositions for the preparation of a medicament for the treatment of dermatoses, such as, in particular, acne, cutaneous ulcers, warts and dyskeratinizations of the skin. skin.
- dermatoses such as, in particular, acne, cutaneous ulcers, warts and dyskeratinizations of the skin. skin.
- compositions in accordance with the invention, may be used for the cosmetic treatment of the skin, especially as a cleaning and disinfecting, comedolytic, keratolytic product.
- Another object of the invention relates to a cosmetic treatment process characterized in that it consists in applying to the skin a composition according to the invention for purifying or purifying the latter.
- This composition is used as a skin cream once or twice a day for one to twelve weeks.
